Figure 6.

Variations in the initial disturbance of the initial morphogen field results in a number of patterns comparable with the different patterns seen in species of Pomacanthus. Initial disturbance is marked by the region within black rectangle. (a) A disturbance cranial to the tail result in formation of ring patterns, compare with P. imperator (Fig. 1d). The disruptions to the patterning close to the boundaries compares with the disruptions observed in juvenile P. imperator. (b) The disturbance occurs at the tail, resulting in semicircular stripes reminiscent of juvenile P. semicirculatus (Fig. 1 a–c). (c) Larger initial disturbances can result in stripes of little curvature, which occur in juveniles of the species P. striatus. (d) An even larger initial disturbance can robustly generate stripes. Simulations use same chemical kinetics and parameter values as in Fig. 3, however, similar patterns are obtained for nonlinear kinetic schemes. All plots show activator concentration (u).
